Synthesis, Characterization and Photocatalytic Performance of Poly-3-Thenoic Acid/Cu-TiO2 Nanohybrid for Efficient Visible Light Assisted Degradation of Bismarck Brown R

The present work reported on the synthesis and characterization of Poly-3-Thenoic acid/Cu-TiO2 nanohybrid (PCuT) for photocatalytic degradation organic azo dye pollutant from wastewater. as-synthesized by an in-situ modified sol-gel method including chemical oxidative polymerization was characterized X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, UV-visible diffuse reflectance spectroscopy (UV-vis.DRS), scanning electron microscopy with energy-dispersive (SEM-EDX), transmission (TEM) Brunauer-Emmet-Teller (BET) surface area analysis. results revealed formation small aggregates polymer contained high crystalline anatase TiO2 nanoparticles (XRD) narrowed bandgap energy decreased particle size smooth morphology (SEM) large (BET). All constituent elements Cu-TiO2 were found in PCuT material (EDX) their interaction studied FT-IR confirmed stability nanohybrid. activity tested Bismarck Brown R under visible light irradiation. To enhance efficiency, effects various catalyst/dye reaction parameters such as content, solution pH, catalyst dosage, initial concentration optimized.
